Thanks very much. I'll order one up!

Registered but can't access Bob. Any recommendations for sourcing a plug spanner that will fit an ER5?

Thanks for this. I'll have another go. Yes I've registered with the ER5 forum

Update. Remove carbs, cleaned and replaced needle valves, pilot jet and float chamber gasket. Removed fuel filters, cleaned and blew the pipes through. Changed the oil and filter (again!). Started first time and ran well. Left alone for a week due to work commitments and it's overfuelling again! Just out of interest, how many turns on the pilot jet?

Thanks again, I'll have a go at that. I'll report back!

When I the bike the sump was full of fuel. As the fuel tap was left on "prime" I assumed that was the problem. Drained the crap, changed the filter and refilled with new oil. Then noticed all fuel lines to the petcock were disconnected or removed. Haynes doesn't make things too clear so I had to work it all out. Put a couple of litres of new fuel in the tank and she fired up first time. Settled down when warm and ran sweet. Noticed a leak from the "out" on the petcock so put a new one on and put a few more litres in the tank. All went well for about 5 mins then she cut out and won't restart. Noticed fuel leaking out from the bottom of the RH carb. Any ideas?

Thanks Fastbob. Might be quite a few!

Speedo drive misaligned! Thanks everybody, lesson learnt there...

Good thought fastbob. I'll give it a go.

Thanks all! I'll try all these and let you know what happens

Doing a 2000 Er5 up as a light restoration. Bike has been in the previous owners garage unused for some time. I set about removing the front wheel to remove the front forks and noticed that the spindle nut (not pinch bolt) was very loose and the wheel rotated freely. I did the job on the forks and when I fitted the front wheel back in place I couldn't put the correct torque on the spindle nut without the wheel stiffening up to the point where it was difficult to move at all. I've checked to see if any components are missing from the spindle assembly but that doesn't appear to be a problem. Getting frustrated now because it must be something simple. Any ideas anyone?
